Nigella damascena, often called Love-in-a-Mist for its delicate blooms surrounded by wispy foliage, is a beloved annual flower prized for its unique beauty. But how do you cultivate these charming plants from scratch? This article explores sowing Nigella damascena seeds, guiding you through both direct sowing outdoors and starting seeds indoors for earlier blooms. With a little planning and these simple steps, you’ll be well on your way to a stunning display of Nigella damascena in your garden!
In this study we report the development of effective in vitro systems for a medicinal plant Nigella damascena L. comprising:
(1) callus induction, (2) somatic embryogenesis in callus cultures with subsequent plant regeneration, and (3) isolation
and regeneration of callus-derived protoplasts. Callus development was achieved on 83–100% of hypocotyl and cotyledon
explants, whereby Murashige and Skoog medium (MS) supplemented with 3 mg L−
1 6-benzylaminopurine and 0.5 mg L−
1
α-naphthaleneacetic acid (NAA; BN medium) was more advantageous than MS with kinetin and NAA (KN medium). Histological
observations of calli revealed the presence of embryogenic zones from which somatic embryos developed on the
hormone-free medium. Plant regeneration was observed on 76–95% of calli. A high capacity to form somatic embryos and
regeneration was maintained in long-lasting cultures, i.e. even in 2 year old callus.
The obtained callus was also a good source tissue for protoplast isolation. By applying a mixture of cellulase and pectolyase,
the acceptable yield of viable protoplasts was achieved, especially from hypocotyl-derived callus maintained on BN medium.
Protoplasts embedded in an alginate matrix and cultured in modified Kao and Michayluk media re-constructed their cell
wall and re-entered mitotic divisions. About 30% of small cell aggregates formed microcalli, which, after the release from
alginate, proliferated continuously on KN and BN media, irrespective of the tissue variant used as the protoplast source.
Somatic embryo formation and plant regeneration were successful on hormone-free media. An effective plant regeneration
system of N. damascena protoplast cultures has been developed and is being reported for the first time

Micropropagation, also known as plant tissue culture, is a powerful technique for rapidly multiplying desirable plant varieties. This article delves into the intricate world of micropropagation, exploring its principles, procedures, and extensive applications. We’ll unveil the fascinating journey of transforming tiny plant tissues into a multitude of genetically identical offspring within a controlled laboratory environment.
The bromeliad Tillandsia eizii is a striking species with large, colorful, and persistent inflorescences that can reach 1 m in length. The value of this plant as an ornamental and its importance in cultural and religious activities has led to its over-collection in the wild. Clonal propagation via tissue culture may be a means to repopulate native stands while meeting the demands for this species as an ornamental and ceremonial plant. Adventitious bud proliferation was induced from axenically germinated seedling material. Parameters evaluated were the age of explant material at the time of transfer onto bud-induction medium, the concentration of plant growth regulators, and the period of exposure to induction medium. Light and scanning electron microscopy (SEM) established the origin and development of buds. Twelve-week-old seedling explants rapidly initiated adventitious buds after a 30-d induction period on shoot-initiation medium. Adventitious buds were induced in 40% of the explants placed on media with 2 mg l21 6-benzylaminopurine (BA) (8.88 mM) plus 0.1 mg l21
a-naphthaleneacetic acid (NAA) (0.54 mM) with some cultures becoming highly prolific after repeated subculture. Shoots elongated in proliferating cultures, and plants were successfully acclimatized and planted into the greenhouse. The results indicate that tissue culture may be used as a means to propagate this epiphytic bromeliad species, which is being seriously affected by deforestation and habitat destruction. In addition, adventitious bud proliferation can provide a means to propagate superior genotypes.
Propagating Tillandsia stricta, the popular air plant, isn’t just about aesthetics! It allows you to cultivate more of these unique, low-maintenance plants. While some sources mention stem cuttings, the preferred method is through pups, or offsets. This article explores why pups are the way to go for Tillandsia stricta propagation, guiding you through the separation process and aftercare for your new pup. With a little patience and these steps, you’ll be a pro at multiplying your Tillandsia stricta in no time!
